METAL-LATH ATTACHMENT AND SUPPORT.

SPECIFICATION forming part of Letters Patent No. 657,827, dated September 11, 1900.

Application filed May 2, 1900. Serial No. 15,206. lNo model.)

To all whom it may concern:

Be it known that I,WILLIAM MOOALL,a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Metal-Lath Attachments and Supports; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a means for securing and supporting metal lathing, such as is employed in the construction of fireproof and other buildings.

It consists of the parts and the constructions and combination of parts hereinafter described and claimed.

Figure 1 is a perspective view showing the application of my invention as applied to a ceiling. Fig. 2 is a view of the 'metal-lath attachment. Fig. 3 is a view showing application to a wall. Fig. 4 is a plan. Fig. 5 shows the application to a column. Fig. 6 is a view of a modification. Fig. 7 shows application to ceiling-beam. Fig. 8 shows a modification of the hooks. Figs. 9 and 10 are detail views of the transverse strips.

The objects of my invention are to provide a means for rapidly attaching the sections of wire or expanded metal laths to the partitions, ceiling, or other portions where the lath and plastered surfaces are to be applied and to form a plurality of supports and attachments, so that the lathing is firmly held in ing away from the support when the plaster is applied or under other conditions.

I have here illustrated myinvention as applied in various ways to structures where it is desirable to apply lathing.

A represents the support to which the lath is to be applied, which may be a vertical or horizontal partition or ceiling surface, or an intermediate plate attached to brick or other walls, or to columns to form a support for the lathing.

The lath-supporting structure A may be formed of parallel vertical or horizontal strips,

. upon the edges of which the tongues 2 are formed, and these strips are united to form a rigid structure by intermediate transverse strips or bars 3, which have tongues 8 at the ends,formed by slitting the ends transversely. These tongues pass through corresponding strips or bars 3.

place and is prevented from sagging or pullslots or openings in the strips A and may afterward be folded, twisted, or otherwise locked firmly to them. The edges of the strips A may be bent at right angles to form flanges 9 between the hooks, .thus stiifening the strips when made of light or thin metal.

In order to support the strips A when used for ceiling purposes, the ends are cut away, as shown at 10, to correspond in shape with the lower flanges of the I-beams of the floor above, over which these ends extend toward the vertical web. The strips thus present a vertical depth sufficient to prevent sagging and are stiffened horizontally by the flanges 9 as well as by the intermediate connecting It will be understood that the same construction used as a vertical partition would have its upper and lower ends properly secured to the ceiling-beams and floor. The tongues or spurs 2 then project from the lower surface of these strips A and are in position to receive the lathing.

If the lathing is to be attached to a brick or other wall where it is desirable to have an air-space between the wall and the plastered surface, the strips A are bent into a curved or V shape or other desired form having flanges, as shown at 5, which flanges are perforated, so that nails can be driven through the holes and into the mortar-spaces between the brick or other material of which the wall is formed. The strips A are thus secured to the wall, and the outer curve or angle is then slit, as shown, so as to form the projecting tongues 2, which are bent outwardly to receive the laths.

If a column, such as is shown at 6, is to have a plastered surface, the strips A may be made either V- shaped or slightly curved and of a length sufficient to extend vertically up and down the column which is to be covered, and they may be secured in place .with their open bases against the column, the angular portion presented outwardly, and the tongues 2 are cut out from these angular portions, as before described. The strips A in this case are secured to the oolums by wires around them at intervals or by othersuitable means.

The lathing, which, as before stated, may be of wire, expanded metal, or sheets of any description having interstices through which the mortar will pass to form a bond, are then rapidly hooked upon the projecting tongues hung upon the points the latter are .bent or closed down, so as to lock the lathing in place, by a tap of a hammer or other means, and

the whole is firmly secured and supported.

ready to receive the plaster.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with parallel strips having slot-s, of transverse strips having their ends passed through said slots and trans versely slit-ted to form tongues adapted to be bent to lock the transverse stripto the parallel strips.

2. A support for metalliclathing consisting of metallic plates, means for securing said plates to the Wall, partition or ceiling to be covered, transverse connections having ends passed through the plates and locked thereto by twisting or bending, and tongues formed by slits made in the part to which the lath is to be attached, said tongues having the base connected with the support, and the point projecting outwardly therefrom.

3. The combination with a supporting-base of plates or strips of sheet metal having slits out upon the sides to form tongues with one end remaining attached to the strip, said strips extending over the lower flanges of the I-beams, and having one or both edges turned at right angles with the vertical depth of the strips, and transverse connections having ends passed through the strips and locked thereto.

4. Supports for metallic lathing consisting of parallel strips of metal having slits out to form projecting tongues upon the edges,transverse strips or bars having the ends formed to pass through corresponding slots in the adjacent parallel strips and adapted to be locked thereto by twisting or bending.

In witness whereof I have hereunto set my hand.

WILLIAM MOCALL.
